Abstract

In a method for manufacturing a multilayer ceramic electronic device, a resin introduction portion located outside a vertically projected region of a surface mount electronic device is disposed on a seat portion which includes a non-metallic inorganic powder as a primary component and on which the surface mount electronic device, e.g., a semiconductor element, is mounted, and a resin is supplied to the resin introduction portion so as to fill the resin into the seat portion and a gap between the seat portion and a multilayer ceramic element assembly. Unsintered ceramic base material layers and shrinkage restriction layers arranged to restrict shrinkage of the unsintered ceramic base material layers in a direction substantially perpendicular to a thickness direction of the unsintered ceramic base material layers are laminated and, thereby, an unfired multilayer ceramic element assembly is formed, which does not shrink in a direction substantially perpendicular to a lamination direction in a firing step.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an electronic device and a method for manufacturing the same. In particular, the present invention relates to a multilayer ceramic electronic device in which a surface mount electronic device is mounted on a multilayer ceramic element assembly and a method for manufacturing the same.[0003]2. Description of the Related Art[0004]In recent years, performance of electronic devices in the electronics field has improved significantly and contributed to increased information processing speeds, miniaturization of apparatuses, and expansion in functionality of information processing apparatuses, e.g., large-scale computers, mobile communication terminals, and personal computers.[0005]A multi-chip module (MCM) in which a plurality of semiconductor devices, e.g., very large scale integrations (VLSIs) and ultra large scale integrations (ULSIs), are mounted on a ceramic substrate has been used for su...
